Below is how this adaptor diverts the skype calls:

skype call comes--->
skype call is diverted to home phone(we suppose you connect your home phone to the adaptor), then skype call is in the local telephone network(PSTN)

---> your home phone dials your cell phone(your cell phone's LCD will display your home phone's number), in fact, due to skype calls are in your local telephone system, so skype calls can reach any phone number as long as your home phone can reach.

Assuming L1 is your Verizon telephone number, the one "on the wall", L2
is the standalone telephone attached to the adaptor, and L3 is your cell
number.
Assuming that using the adaptor, you forward the calls to L3 after 5
rings.

a. if you receive a call on L1, L1 will ring
b. if you receive a Skype call, L2 will ring, and after 5 rings, L3 will
ring

if someone is using our AU-600, you can divert your skype calls to any phone number by his/her AU-600.
For example: If John is using our AU-600, and you know John can be reached at 1-555-555-5555 at this monment and John does not configure his AU-600 to divert his skype to that phone number, then you can use John's AU-600(John does not need do anything) to forward your call, then your skype call can be forwarded to 1-555-555-5555. of course, You have to know John's password(AU-600).

If both sides are using this adaptor:
For example, I am in the US and have this adapter. My friend in UK also has this adapter. If I set up the forwarding for both adapters, I can call from my cell phone to my friend's cell phone in UK.
What I am thinking is:
1. I use my cell phone to call to make skype call from US.
2. My adapter will forward my call to Skype and connect to the my friend Skype in UK.
3. In UK, the adapter will forward the Skype to my friend's cell phone.

==> I can make a phone call from my cell phone to my friend's cell phone.
The cost is: local cost from my cell phone to my landline + the local cost from my friend landline to his cell phone.
